THE MOMENT IN AVALANCHE ALMOST SWEPT THEM DOWN THE MOUNTAIN. WE HAVE THEIR STORY. THIS WAS SUPPOSED TO BE A BIG FAMILY ADVENTURE. THE GOAL WAS TO SET A WORLD RECORD FOR THE YOUNGEST CHILDREN TO CLIMB A NOTORIOUS DAY -- NOTORIOUSLY DANGEROUS MOUNTAIN. IN AVALANCHE PULLED THE TWO CHILDREN DOWN THE MOUNTAIN. I WAS PRETTY SCARED. IT CAME REALLY FAST. I FELT LIKE AN ANTELOPE BEING RIPPED DOWN BY A LION. TAKE YOUR TIME. THEY SET OUT TO SUMMIT THE MOUNTAIN. THE NICK NAME -- THE WHITE KILLER. THEY WERE TETHERED TO THEIR FATHER, AN EXPERIENCED CLIMBER. THEIR GOAL WAS TO REACH THE 16,000 FOOT SUMMIT AND SET A RECORD. WE CAME UP WITH THE IDEA TO SET A RECORD FOR THE YOUNGEST BOY AND YOUNGEST GIRL. YOU CAN SEE IT HAPPENED IN A SPLIT SECOND. IN AVALANCHE SWEPT THE CHILDREN OFF THERE PATH. -- OFF THEIR PATH. ALL I COULD THINK OF, I HAVE TO CREATE -- I WAS SORT OF STUCK. SHANNON AND I WERE ON EACH OTHER. OTHER CLIMBERS RUSHED TO HELP. THEY DECIDED TO DESCEND TO SOLID GROUND. THE YOUNG CLIMBERS SAY THEY WOULD STILL BE WILLING TO GIVE THAT SUMMIT ANOTHER TRY. I WILL TRY TO CLIMATE AGAIN NEXT YEAR. WE CAN TELL YOU THE CHILDREN ARE ALREADY BACK TO CLIMBING.
